Technical Manual for EA350 Analog Pulse Type Servo Driver V101 3.2.1 Introduction to the main circuit (high voltage) terminal Table 3-1 Description of the main circuit terminal of the servo driver 24 Terminal marking Terminal name Terminal Function L1C, L2C Control power input terminal Output with voltage consistent with power level of the main circuit (EA350-038, 052 and 062 models don’t contain this terminal) L1, L2, L3 AC power input terminal of main circuit EA350-0R9-1B EA350-1R6-1B EA350-2R5-1B Single-phase 220V input of terminals L1 and L2 EA350-4R8-2B EA350-6R2-2B Single-phase 220V input of terminals L1 and L2 Or three-phase 220V power input of L1, L2 and L3 EA350-010-2B Three-phase 220V power input of L1, L2 and L3 EA350-5R6-3B EA350-8R5-3B EA350-013-3B EA350-017-3B EA350-022-3B EA350-028-3B EA350-038-3B EA350-052-3B EA350-062-3B Three-phase 380V power input P+, D, C Connecting terminal for an external braking resistor Shorting wire is used for connection between P+ and D in default When the braking force is insufficient, leave the circuit between P+ and D open, and connect an external braking resistor between P+ and C.
External braking resistor should be purchased separately. (EA350-0R9, 1R6, 2R5, 017, 022, 028, 038, 052 and 062 models have neither wiring terminal D nor short-circuit wire.) P+, Common DC bus terminal The DC bus terminal of a servo driver can be connected to a common bus in case of multiple units connected in parallel. U, V, W Servo motor connecting terminal The connecting terminal of a servo motor connects to U, V and W phases of the motor. PE ground The two ground terminals are connected to the ground terminals of the power source and the motor.
